When I go to Browse > TIDAL, the screen of my tablet freezes at the TIDAL home page. When I close and reopen the Roon app, the frozen TIDAL screen reappears. When I reboot the tablet and open Roon, the frozen TIDAL screen reappears. The only way I could restore normal function the last time this happened was to uninstall and reinstall the Roon app.
I am using Roon 1.8 (build 806) from a Samsung tablet that accesses the core on a desktop computer running Debian 10 (Linux). The audio zone is a Bluesound Node 2i connected to a McIntosh amplifier. All of connections between the router, the desktop, and the Node 2i are wired. I use the TIDAL streaming service.
